Q. No .8 A spherical pressure vessel has an inside diameter of 4 m and a wall thickness of 15 mm. The vessel will be constructed from structural steel [E = 200 GPa; v 0.29] that has a yield strength of 250 MPa. If the internal pressure in the vessel is 1,200 kPa, determine (a) the normal stress in the vessel wall, (b) the fac- tor of safety with respect to the yield strength, (c) the normal strain in the sphere and (d) the increase in the outside diameter of the vessel.

Integrated Solid Waste Management

Integrated Solid Waste Management (ISWM) is a thorough waste suppression, compost, removal and recycling Program. An effective ISWM system considers how to suppress, manage and recycle solid waste in a manner that is most efficiently to protect human health and the surrounding. ISWM system requires evaluation of public wants and demands and then selecting and merging the most effective waste management activities for the proposed demands. The main ISWM activities for solid waste management are Waste prevention, Recycling and Composting, and Combustion and Removal and waste collection in a properly planned, constructed, managed and mitigated landfill areas. Each of these requires careful designing, financing, accumulation, and delivery of activities.
